QUESTION: 4

One side of a right triangle measures 12 cm and the difference between the hypotenuse and the other side is 8 cm. The area of the triangle is

Solution:

Let the hypotenuse = x cm
Then the other side is (x - 8) cm
By Pythagoras theorem
(x - 8)2 + (12)2 = x2
⇒ x2 + 64 - 16x + 144 = x2
⇒ -16x = -208
⇒ x = 208/16 = 13 cm
∴ Hypotenuse = 13cm
so the other side = (13 - 8) = 5cm
Area = 1/2 x 12 x 5
= 30cm2
